Im on my second set of yokohamas and love them. I got 55k out of my last set and that is the longest i have ever had a tire last(i drive very hard). As for fitment the 31s fit my 05 with just the smallest bit of rub when stock. I put the bilstine 5100 with 3/4" of lift and have had no problems. You might be able to fit them with just the pinch weld mod(search) on your 01. I never had any problems or flats and found that they do well in wet and dry. Best tire for the money in my opinion.
